Chemical Structure
Description
CATO supplies 4-Bromobenzenesulfinic acid sodium salt dihydrate (CAS 175278-64-5), a certified reference material (molecular formula C6H4BrO2SNaH2O, MW 261.06 g/mol) for analytical method development and quality control.
Based on its molecular formula C6H4BrO2SNaH2O, 4-Bromobenzenesulfinic acid sodium salt dihydrate contains a salt form, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 261.06 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-Bromobenzenesulfinic acid sodium salt dihydrate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
